STAR batsman Kevin Pietersen insists England have shrugged off the after-effects of their Adelaide slump and are ready to mount an Ashes fightback.

The inspirational batsman was as mystified as anyone at their collapse on the final day at Adelaide to allow Australia a six-wicket victory and a 2-0 advantage in the five-match series.

But after several days of contemplation and relaxation, Pietersen is ready to go again to try to deny Australia's hopes of regaining the Ashes in this week's third Test at the WACA, which starts on Thursday.
